The differences between boiled or unboiled bones are not often studied. However, they are crucial to understand postmortem rituals and to establish defleshing procedures and mortuary practices. In this work, human bones boiled in sea or fresh water are characterized. The bone composition, as well as the compounds present in the resulting materials, shows that salt alters the boiling process mechanism. Hence, from structural and morphological criteria, it is possible to distinguish if a bone has been boiled in salt or fresh water. In both sets of samples, the smoothness of the bone surface depends on boiling time, but only in bones boiled in seawater, filaments are observed apparently pouring out of the pores.Those differences which are mainly morphological (smoothness of the surface) are explained in terms of a collagen diffusional mechanism favored by sodium and chloride ions. For a boiling time of 6 h, the surface is covered by a thick layer or crusts of degraded collagen. Experiments with seawater may be used as model experiments to simulate taphonomical alterations in bones exposed to salt water. 相似文献

This article describes the dynamical behavior of free-standing block structures under seismic loading. A comprehensive experimental investigation has been carried out to study the rocking response of four single blocks of different geometry and associations of two and three blocks. The blocks, which are large stones of high strength blue granite, were subjected to free vibration, and harmonic and random motions of the base. In total, 379 tests on a shaking table were carried out in order to address the issues of repeatability of the results and stability of the rocking motion response. Significant understanding of the rocking motion mechanism is possible from the high quality experimental data. Extensive experimental measurements allowed to discuss the impulsive forces acting in the blocks and the three-dimensional effects presented in the response. 相似文献

Performance-based earthquake engineering methodologies often require a probabilistic model of structural demand. Since observations masking the probability distribution of the majority of the data are frequently found, robust estimation methods are proposed to estimate the probabilistic model parameters (i.e., central value and dispersion). The performance of thirty-three robust dispersion estimators is evaluated, for different sample sizes, using the chord rotation, curvature, shear force, and inter-story drift demands obtained after analyzing five reinforced concrete structures under real earthquake records scaled to several intensities. Based on the results, combinations involving dispersion and central value (defined in a companion article) estimators are proposed. 相似文献

In the last few decades many studies have underlined the role of philhellenism in shaping the Risorgimento as a transnational movement. But philhellenism also had a significant impact in embodying the pre-unification Italian state in a new imaginative framework, marked by the binary oppositions of civilized/barbarian, liberal/despotic and north/south. This article analyses the influence of philhellenism in shaping the imagery of the Kingdom of Sardinia in the eighteenth and nineteenth centuries and the role played by this local imagery in promoting opposing patriotisms within the national political sphere in the years leading up to the unification of Italy. Cavour’s moderate party stressed the positive impact of the Piedmontese domination over the island of Sardinia in order to underline Piedmont's image as a force of modernization of a land strongly marked by feudal despotism and pastoral violence. By contrast, Mazzini and the democrats also deployed a philhellenic narrative scheme to explain the backwardness of Sardinia with reference to the despotic and ‘oriental’ character of the Piedmontese domination in an attempt to encourage opposition to unification under the leadership of the subalpine government. 相似文献

Landscapes of the Ghost Dance: A Cartography of Numic Ritual 总被引:1,自引:0,他引:1

Recent historical and ethnographic research indicates that the study of ritual behavior could be greatly enhanced by combining parameters of place and landscape use with interpretation of material culture. This strategy is especially useful for identifying the archaeological record of ritual among societies that incorporated topographic features and natural resources into their liturgical order. In this article we apply a behavioral framework to the study of Numic ritual technologies. By intergrating ethnographic and historic data on the geography, practice, and material culture of the nineteenth-century Nevada Ghost Dance, we demonstrate how this framework helps to determine the configuration of a ritual place and its position relative to other ritual and nonritual places. 相似文献

This study examines the potential socio-spatial impacts of a new series of marine protected areas (MPAs) on fishers in Moorea, French Polynesia. The establishment of the MPAs is contextualized within recent and historical processes of economic development and theories of women in development and gender, culture and development. Seventy adults from three neighborhoods in Moorea were interviewed. Analysis of the data provides new information about the characteristics of fishing in Moorea. Unlike most fishing cultures and communities throughout the Pacific Islands, men and women in Moorea have similar, as opposed to segregated, spatial patterns of fishing activities and fishing methods. The study also points out the potential negative impacts of the MPAs on both men and women, particularly younger and lower-income fishers. 相似文献

A Multiobjective Approach to Locate Emergency Shelters and Identify Evacuation Routes in Urban Areas 总被引:2,自引:0,他引:2
Luís Alçada-Almeida Lino Tralhão Luís Santos João Coutinho-Rodrigues 《Geographical analysis》2009,41(1):9-29
Evacuation planning is an important component of emergency preparedness in urban areas. The number and location of rescue facilities is an important aspect of this planning, as is the identification of primary and secondary evacuation routes for residents to take. This article introduces a multiobjective approach to identify these aspects of evacuation planning. The approach incorporates a multiobjective model into a geographical information systems–based decision support system that planners can access via the Internet. The proposed approach is demonstrated with a case study for the City of Coimbra, Portugal, for evacuation during major fires. Although presented in this context, this approach is applicable to other emergency situations such as earthquakes, floods, and acts of terrorism. 相似文献

The colluvial soils of Galicia (NW Spain) are records of Holocene environmental change. In spite of the omnipresence of charcoal fragments in these soils, the effect of fires on the development of the Galician landscape and the potential role of past societies are poorly understood. 相似文献

Qâni’, the main seaport for the export of goods from South Arabia, was founded by the Hadramawt kingdom in the first century BC. A geomorphological survey and a general surface reconnaissance of Qâni’ have revealed a new image of the site. Originally a royal entrepôt in a fortress on an ancient island, separated from the mainland by a silted channel lined with a mangrove forest, Qâni’ gradually grew and spread around the beach fronting the mooring place of the trade ships that arrived by sea. Sacred spaces, cemeteries, dwellings and trade quarters appear to be well‐defined areas forming a real town within the limits imposed by the surrounding sea. 相似文献
